    Display *dpy = gdk_x11_display_get_xdisplay(gdpy);
    XSetIOErrorExitHandler (dpy, x_io_error_exit_handler, &done);

=>  window = gtk_window_new ();
    gtk_window_set_title (GTK_WINDOW (window), "hello world");

Judging by the absence of arguments to `gtk_window_new', this code is
for GTK 4, correct?

The X and GTK configuration will never work with GTK 4 due to other
fundamental changes in the toolkit, and PGTK will not be able to access
X-specific APIs.

Thanks.
